AHA主席回应到底该不该限盐

2015-02-02 高晓方 译 医学论坛网

1月19日在线发表于《美国医学会杂志·内科学》(JAMA Intern Med)的一项研究显示,低钠摄入对一些老年人群的死亡、心血管疾病和心衰未产生影响。对此,美国心脏学会(AHA)主席于近日指出了该项研究存在的问题,并对引发争议的问题进行了澄清及说明。[JAMA Intern Med:老年人食盐过少或不降其死亡率和心血管疾病] AHA主席 研究的关键局限性 首先,研

AHA主席

研究的关键局限性

首先,研究所采用的食物频率调查问卷在估算每日钠摄入方面并不可靠,标准方法为尿样检测。

其次,调查者假定钠摄入处于稳定状态,忽视了膳食习惯存在的自然变异。

第三,研究样本量过小,因而无法评估AHA推荐的钠摄入效应。

第四,低钠摄入组受试者在入组时更为虚弱并且热量摄入不足,需要更多的医疗诊治。

AHA主席指出,鉴于这项观察性研究的上述严重缺陷,不应将该研究结果用于老年人群膳食推荐,也不足以让其重新考虑AHA的有关钠的推荐。

他还强调,除非存在特定疾病或特殊环境,否则所有人群每日钠摄入均应少于1500mg。大量证据表明低于1500mg钠摄入对心脏健康更为有利,超出上述水平则会增加高血压卒中风险。医务人员、监管机构和患者不应为诸如此类的问题研究所困扰,而应继续贯彻相关措施以减少人群钠摄入。

AHA/ACC提出临床数据标准化定义

刀币、布币、环钱……,秦统一前各诸侯国的钱币可谓形态各异,这大大阻碍了当时的经济发展。当前,收集上来的临床数据也是凌乱的,同样羁绊了医学前进的脚步。 为了构建更为优良的数据环境,美国心脏病学院(ACC)/美国心脏协会(AHA)的临床数据标准工作组与美国食品药品管理局(FDA)和心血管试验标准数据采集联盟(SCTI)合作阐述了关于“为临床试验和健康相关研究制定通用语言迈步”的标准。

郭艺芳点评:强效降胆固醇:大剂量他汀还是常规剂量他汀联合依折麦布?(IMPROVE-IT研究)

2014年AHA年会期间揭晓了IMPROVE-IT研究结果。近年来,此研究一直受到广泛期待。之所以如此,是因为这项研究或可回答两个至关重要的问题:(1)降胆固醇是硬道理还是他汀是硬道理?已有充分证据显示,应用他汀降低胆固醇水平可以显著降低心血管病患者及其高危人群不良心血管事件的发生率。但应用其他药物降低胆固醇水平是否产生同样的获益尚不清楚。(2)当LDL-C处于较低水平时继续降低其水平可否进一步获

AHA 2014:缺氧和低血压对外伤性脑损伤有协同负面效应

AHA 2014科学年会的一项报告表明,院前缺氧和低血压可对外伤性脑损伤(TBI)患者产生协同负面效应,导致死亡风险相对于单一因素显著升高3倍以上。14 此项研究共纳入9194例中重度TBI患者,并以氧饱和度<90%定义缺氧,以收缩压<90 mmHg定义低血压。对年龄、性别、种族、付款来源和创伤治疗中心等混淆因素进行校正之后,利用比值比(OR)评估死亡率与缺氧和/或低血压之间
